In one embodiment, as shown in Fig. 2 before above-mentioned steps S102, method can also be implemented as following steps
S201-S202：
In step s 201, the target hash function that receive user sends；
In step S202, the target cryptographic Hash of file to be verified is calculated according to target hash function.
User will can in advance save from damage in the block chain that user carries out ideal money transaction for the file of checking.Separately
Outward, because block chain is not to design for data storage, low volume data can only be stored, for example, the cryptographic Hash of original document, because
This, user can be stored in file to be verified corresponding cryptographic Hash in the transaction of block chain, to realize the guarantor to file to be verified
Entirely.Because block chain stores all transaction having been acknowledged, and because cryptographic Hash is unique, just may certify that this
The presence of the corresponding file of cryptographic Hash.
It should be noted that the corresponding cryptographic Hash of the file to be verified can be the file to be verified cryptographic Hash of itself.
It can also be the final hash value of the file to be verified of multiple format.
When the final hash value of the file to be verified of multiple format is calculated, the various of the file to be verified are obtained in advance
Preset format, Hash calculation is carried out according to default hash function to the file to be verified of these preset formats, obtains various pre-
If the cryptographic Hash of the file to be verified of form, then the multiple cryptographic Hash for obtaining are carried out according to the default hash function secondary
Hash calculation, obtains the final hash value of the file to be verified.
Due to user carry out saving from damage when data are saved from damage be file cryptographic Hash, thus, in the present embodiment, judging target
Before whether there is target transaction corresponding with the file to be verified in block chain, method also includes, the mesh that receive user sends
Mark hash function, according to the target hash function target cryptographic Hash of the file to be verified is calculated.In the present embodiment, calculate to be tested
The target cryptographic Hash of card file is right to realize so that the cryptographic Hash stored when subsequently saving from damage with file in block chain is compared
The checking of file to be verified.
In one embodiment, as shown in figure 3, above-mentioned steps S202 can be implemented as following steps S301-S303：
In step S301, obtain various preset formats of file to be verified, wherein, various preset formats include with down to
A kind of few form：
Unprocessed form, extensible markup language form and number format；
In step s 302, Hash calculation is carried out to every kind of preset format according to target hash function all default to obtain
Cryptographic Hash corresponding to form；
In step S303, secondary Hash is carried out to the cryptographic Hash corresponding to all preset formats according to target hash function
Calculate to obtain target cryptographic Hash.
In the present embodiment, various preset formats of file to be verified are obtained.Wherein, the preset format of the file to be verified with
Its form for carrying out calculating when data are saved from damage used in cryptographic Hash is consistent, so as to ensure the uniformity of cryptographic Hash.
Respectively the file of every kind of form is carried out Hash calculation to be owned according to the target hash function that user sends
Cryptographic Hash corresponding to preset format.Wherein, make when the target hash function is saved from damage by user to the file to be verified
Hash function.
Two are carried out to the hash function corresponding to the file of all preset formats according to the target hash function that user sends
Secondary Hash calculation, so as to obtain the corresponding target cryptographic Hash of the file to be verified.
Due to carrying out Hash calculation twice in the present embodiment, thus, even if other users obtain the file to be verified, it is such as
Fruit does not know the file format used when target cryptographic Hash is calculated, and cannot obtain the target cryptographic Hash yet, further improves
The security of file.
The beneficial effect of the present embodiment is：By carrying out Hash calculation twice to file to be verified, so that target is breathed out
The computation rule of uncommon value is more complicated, and increases the difficulty that other users obtain target cryptographic Hash by file to be verified, is entered
One step improves the security of file.
In one embodiment, when target data includes transaction ID, as shown in figure 4, before above-mentioned steps S103,
Method can also be implemented as following steps S401-S405：

In step S402, when the transaction corresponding to presence and transaction ID, judge that the number of times that transaction is confirmed is
It is no to reach preset times；
In step S403, when the number of times that is confirmed of transaction reaches preset times, the recorded in transaction is obtained
One cryptographic Hash；
In step s 404, the first cryptographic Hash is compared with target cryptographic Hash；
In step S405, when comparison result is consistent, determine exist in target block chain it is corresponding with file to be verified
Target transaction, and target transaction is to record the transaction of the first cryptographic Hash.
In the present embodiment, judge to whether there is and the transaction corresponding to transaction ID in target block chain.
Data structure in block chain is similar to stack architecture.Thus, user when carrying out file and saving from damage, by file correspondence
Cryptographic Hash when sending to the block chain for being encrypted moneytary operations, equivalent to the corresponding cryptographic Hash of the file saved from damage is put
In stack top.
Due in storehouse edlin can only be entered to the data of stack top, thus, with constantly carrying out for encryption moneytary operations, stack
Top position is replaced by these corresponding transaction data of transaction.Also, the not modifiable principle of block chain is that a transaction is added
Enter in a block, needs obtain the confirmation concluded the business for 10 minutes, all blocks afterwards all can often increase by one comprising the transaction
Individual block means newly-increased once to confirm.Thus, the time is more long, and the confirmation number of times of acquisition is more, and transaction more is difficult to be tampered.Cause
To want to modify, it is necessary to reconfigure block below.When the final block length for creating exceedes former main split block, into
For new main split.That is, other people want to distort transaction, its equipment must possess the calculation than block chain the whole network
Power also wants powerful calculation power, is only possible to distort transaction, and not currently exists such equipment.Thus, due to other
People cannot enter edlin to the corresponding cryptographic Hash of file saved from damage.Improve the security of file.
Therefore, when the transaction corresponding to presence and transaction ID, judge whether the number of times that the transaction is confirmed reaches
Preset times, when the number of times that the transaction is confirmed reaches preset times, then the corresponding cryptographic Hash of the file saved from damage is
Cannot be tampered.
Therefore when the number of times that the transaction is confirmed reaches preset times, obtain the first Hash recorded in the transaction
Value, and the first cryptographic Hash is compared with target cryptographic Hash.
When comparison result is consistent, determine that there is target corresponding with file to be verified in the target block chain hands over
Easily, the target transaction is to record the transaction of first cryptographic Hash.I.e. the file to be verified before the target transaction is carried out just
Jing is present.
It should be noted that the present embodiment is applied to the feelings that user oneself is saved from damage by block chain to file to be verified
Condition.When user is stored in file to be verified corresponding cryptographic Hash in block chain, generate for saving the file to be verified from damage
Transaction and the corresponding mark of the transaction, such user can obtain the mark of the transaction.To enable notary organization to pass through to use
The transaction ID that family sends inquires corresponding transaction.
The beneficial effect of the present embodiment is：When presence in target block chain and the transaction corresponding to transaction ID, need
Whether the number of times being confirmed that judges to conclude the business reaches preset times.After transaction obtains the confirmation of certain number of times, unless set
Standby calculating speed is more than the whole network speed, otherwise just cannot enter edlin to the first cryptographic Hash in the transaction.Avoid other use
Family is modified by the first cryptographic Hash.Improve the security of file.
In one embodiment, when target data not include transaction ID when, as shown in figure 5, above-mentioned steps S103 it
Before, method can also be implemented as following steps S501-S503：
In step S501, judge to whether there is second cryptographic Hash consistent with target cryptographic Hash in target block chain；
In step S502, when there is second cryptographic Hash consistent with target cryptographic Hash, the second cryptographic Hash of record is judged
The number of times that is confirmed of transaction whether reach preset times；
In step S503, when the number of times that the transaction for recording the second cryptographic Hash is confirmed reaches preset times, it is determined that
There is target transaction corresponding with file to be verified in target block chain, and target transaction is to record the transaction of the second cryptographic Hash.
In the present embodiment, judge to whether there is second cryptographic Hash consistent with target cryptographic Hash in target block chain；When depositing
In second cryptographic Hash consistent with the target cryptographic Hash, judge that the number of times that the transaction for recording second cryptographic Hash is confirmed is
It is no to reach preset times.
When the number of times that the transaction for recording the second cryptographic Hash is confirmed reaches preset times, determine and deposited in target block chain
In target transaction corresponding with file to be verified, and target transaction is to record the transaction of the second cryptographic Hash.
It should be noted that the present embodiment is applied to user's commission third party security mechanism by block chain to text to be verified
The situation that part is saved from damage, and third party's security mechanism is after by removing block chain file to be verified being saved from damage, not
Transaction ID can be provided a user with.Thus, when user needs to verify file to be verified, can only provide when being saved from damage
The hash function for being used and the file format for being used.Thus, when cannot obtaining transaction ID, user can only be passed through
Whether the hash function and file format of offer is inquired about in block chain and is deposited calculating the corresponding target cryptographic Hash of file to be verified
In the cryptographic Hash consistent with the target cryptographic Hash.
The beneficial effect of the present embodiment is：When transaction ID cannot be obtained, target area is judged by target cryptographic Hash
